    This function takes an arbitrary number of iterable arguments and returns a list of tuples,
    where each tuple contains the next item from each of the argument iterables. If the iterables
    are of unequal length, missing values are filled with the `fillvalue`.

    Parameters:
    *args: An arbitrary number of iterable arguments.
    fillvalue: The value to use for missing values in the shorter iterables.

    Returns:
    A list of tuples with the next item from each iterable.
